a cap inserted from the ably arranged to Patented May 165. i933 unrrnn CAEE'IING Application filed duly 8, 1929,

This invention relates to animprovement in capping machines imwhich the bottles are forwarded continuously to one or more capping heads where each bottle is provided with tools which make the cap, or from a container for caps. If there are several capping heads, these are preterrotate in an annular path aloout a common shaft or column and under each capping head is a bottle, placed on a suitalole base rotating together with the capping heads.

The construction of the present invention is such that should a capping head, on any occasion, not receive a bottle. (which might occur specially in the case of automatic supply of bottles), a cap would be prevented from heing forwarded to the said head, which cap would hinder the following cap and interrupt the working. lit the caps are stamped out and bent in the same machine and at the same time as they are fed into the capping head or heads, the arrangement might be made such that the stamping and other operations are interrupted until a head with a bottle again approaches-that place at which the cap is to be inserted in the head.

Am embodiment of the invention is shown in the accompanying drawings, in which Figure l is a perspective view of a capping machine to which the invention has been applied, Figures 2 and 3 show a part of the machine frame in two vertical sections at right angles to each other, Figure 2 showing a side view oi the invention, and Figure 3 an end view. Figure 4c shows a detail. Figs. 5 and '6 are detail plan viewsot the pneumatic cap feeding means. I

The capping'heads 1 (Figure 1) rotate in a continuous manner round a column 2 in the machine frame 8. opening 3 for the insertion of the insertion is efiected when the head 1s turned up to a table or the like 4 on which the cap is made. The cap is stamped out 0 an aluminum strip ted between two rollers 5. Then when the head 1 passes under a roller 17, the capping is efiected in a known manner. The stamping out and the bending are efiected with the same tool 6 the construction Serial No. 376.511, and in Great ltritain January it,

Each head has an,

the cap, and

nacnrnn non nor'rnns an'n man man being of any known type. The cap ready stamped 18 either forwarded to other tools for further treatment or directly into the capping head. The conveyance is edected automatically, for instance pneumatically. The stamping tool 6 is fastened to a slide bloclr 7 in the frame 8., and the movement of the said slide hlock is eiiected by a connecting rod 9 and an eccentric 10, on a shaft ll. 'By means of worm gear 12. a vertical shaft 13., and worm gear 14, 22 (Figures 2 and 3) the shaft 131 is driven from a horizontal shaft 15, which by means of toothed gearing T6 is in driving connection with the driving shaft of the machine, the latter not shown. All these parts are mounted in the trame. The bottles are placed on an endless conveyor belt 18., and conveyed theretromeach to one recessin a nave or the like 19 where the loottle is placed on a support (not shown) pushing up the bottle automatically into the head 11.- above. The nave as well as the supports rotate synchronously with the heads 1. As. soon as a bottle is capped, the support descends and the bottle is removed. The construction thus far described is old in the art.

The operation of the machine is such that the shaft makes one revolution or a cap is made each time a bottle is forwarded to the capping position, so that the cap may he inserted in the head at the right moment.

According to the invention the machine is constructed in such a manner that the stamp tool is stopped whenever the head 1 which is to he provided with a cap has not received a bottle. For this purpose a disengaging cou= pling is arranged in the driving connection between the shafts 11 and 15. This coupling may be constructed in various ways. In the coupling s'hownin'the drawings a pin 20 is axially mounted in a coupling hon 2i rotating with the shaft 15 and normally actuated by a spring inserted in a hole in the worm wheel 22 loosely mounted on the shaft 15. This 95 f wheel is thus coupled with the box 21 and the shaft 15. It abottle is missingythe pin 18 disengaged from the wheel 22 by means of a lever 23 mounted in the frame 8. The'lever' is actuated by a sprin 24 tending to move the lever to a position w ere its lower bevelled I it lost contact with the feeler.

end 25 comes in contact with a shoulder 26 on the pin during the rotation of the shaft 15, the bevel surface moving the pin out of the hole in the wheel 22. However, the bevelled 5 end 25 of lever 23 is normally prevented from engaging the shoulder 26 by the inner end of a rod 28 passing through the fore wall 27 of the machine frame. The rod in its turn is held in this position by a feeler 29, the position of which is fixed by the bottles.

The said feeler is rotatably mounted about a vertical bolt 30 in the frame, and provided with. a surface 41 curved according to the path of the bottles, the feeler being so positioned pass it. The outer end of the rod 28 is supported against a surface 32 of a part 33 combined with the feeler. As long as no bottle is missing on the support table, a preceding bottle will not have left the feeler before the next bottle has come in contact with the same preventing it from being reversed. llf, on the other hand, a bottle is missing, the feeler is reversed under the action of a pressure spring 3& on the rod28 as soon as the preceding bottle has passed. The spring is supported with one end. against a bearing 35 for the rod and the other end against a ring 36 fast with the rod. When, due to the absence of a bottle from the supporting table, the feeler 29 is reversed the rod 28 is Withdrawn by spring 34 from engagement with lever 23 so that the spring 24 may then rock lever 23 and move the trip 25 into the path of shoulder 26 on pin 21. Figure-2 shows the part 33 and the rod 28, Figure 4C the feeler 29 in full lines in inactive position and in dot and dash lines in activeposition. Thus as soon as the shaft 15 has turned the pin 20 up to the lever 23, the coupling is disengaged, if the feeler were about to reverse owing to the fact that there is no bottle in position so as to lock the lever 23 and keep the coupling engaged. lln the position shown the lever is held back by a cam 38 on the coupling box 21.

For adjusting the arrangement for bottles of difi'erent diameter the part 33 is stepped so as to form a number of stop surfaces 32, here shown three in number, at different distances from the centre of the bottles, and the said part is adapted to be raised and lowered (by means not shown) so as to place any of these 1 surfaces in engagement with the end of the rod 28. By this, the feeler 29 will take up different distances from the said centre.

Referring now to Figures 5 and 6, the cap is blasted from the stamping tool 6 along a guider 7* into a head a and is held in position over the bottle until the head comes under the roller 17, when it is then applied to the bottle. The blasting mouth is indicated at m.

If now there is no'bottle in a head, the feeler 29 moves to the position shown in Figure 6. The last bottle is below the head a and has Below the head that the bottle must turn it in a direction to 6 there is no bottle, and the spring 34: (see Figure 2) therefore removes the feeler as shown, and the stamping tool is stopped But it should be observed that the heads continue their rotation as they are driven independently of the stamping tool. The conveyance of the bottles through the machine is shown by arrows, the bottles being indicated by f. The cap may be conveyed into any head whatever provided that the feeler 29 is arranged in a corresponding position. The guide 1" may for instance be directed against the head 6, if the feeler is arranged from b to 0 instead ,of, as shown, from a to I), If so, the stamping tool stops when the last bottle and the head b respectively have come to the position shown in Figure 6. Then the heads may rotate until the head Z2 has passed under 17.

Thus there is never any cap left either outside or in a head when the last bottle is capped. This is an advantage if there is to be capped a new set of bottles of different kind or size, or if the caps are to have another appearance, color, stamp or the like.

The arrangement may, of course be varied in many ways with regard to the details, and may be adapted for controlling the function of other vital parts of the machine.
